This part of IEC 6xxxx specifies product and performance requirements for devices part of “monitoring and measuring systems used for data collection, gathering and analysis”, for industrial, commercial and similar use rated below or equal to 1 kV a.c. and 1,5 kV d.c. These devices are fixed-installed and are intended to be used indoors, as panel mounted devices, or as modular devices fixed on a DIN rail, or as housing devices fixed on a DIN rail, or as device fixed by other mean inside a cabinet. These devices are used to upload or download information (energy measured on loads, power metering and monitoring data, temperature information …), mainly for Energy Efficiency purposes. These devices are known as energy servers, energy data logger, data gateways and I/O data concentrators. NOTE – These systems are embedded or can be connected to a software application capable of consolidating data and delivering automatic analysis. Automatic analysis can include calculation of energy baselines or energy performance indicators as requested for Energy Management System required by ISO 50001, or can be used during Energy Audits as defined in ISO 50002, or can be used for monitoring of installation complying with IEC 60364-8-1. These devices can also be used for certification according to labels such as LEED, BREEAM , HQE, … This standard does not cover: – Devices used only in the consumer market (living area) or household. – Devices used in the smart metering infrastructure (e.g. smart meters). – Devices used in the smart grid infrastructure. – Devices used as IT servers in the Information Technology business – Power Meters (PMD as defined in IEC 61557-12) with additional functions (e.g. Energy Data Logger function). – I/O data concentrators already covered by a specific product standard – Communication protocols and interoperability
